I love these ankle weights. I ordered a pair about ten years ago, following physical therapy. I use them for my 30-45 min. exercise routine in the pool. I also do lap swimming in my workout. I suffer with low back conditions and the weights act like traction. They also give me a weight bearing activity. They have held up great! Last year the fabric finally started to stretch and get holes. But for ten years of 2-3 x a week in the pool, I 'd say that is outstanding! I never took the individual weights out. The Velcro straps held up well too.
